Specification of Letters Patent.

Patented ct.8,1918.

0rgnal application filed March 21, 1916, Seral No. 8 5,583. Divded and this application fi1ed April 14, 1917. Serial No. 162,107.

T0 aZZ whom z't may concern.

Be it known that I, ALBERT T. L0rrs GAARDEN, eitizen of the United States, residing at Powell, in the county of Park and State of Wy0ming, have invented certain new and useful Improvements in Door- Closers, of whieh the following is a specification.

My present invention pertains to springactuated door-closing devices, and the present appiication is a division of my prior appiication fi1ed March 21, 1916, Serial N0. 85,583. The present invention contemplates the provision of a simple, strong and easilyapplied device, calculated to quickly return a door to and retain the same in its closed position.

The invention a1so oontemplates the provision in a door cl oser of improved braokets, susceptible of. ready eonneetion to a door frame and door and constructed in such manner that the leverage and the tension of the retractile spring aan he easily adjusted 01 regulated to fit the door to whioh the eloser is applied.

In the aecompanying drawings whieh are hereby made a part hereof:

Figure 1 is a horizontal section taken through a door frame and a door and showing in plan a door closer eonstrueted in accorda-nce with my invention.

Fig. 2 is an enlarged detail view of one of the brackets.

Fig. 3 is a view similar to Fig. 1 and showing a modification.

Referring by numeral to the drawings and more particularly to Figs. 1 and 2 thereof:

1 is the side stile of a door frame, and 2 is a door hinged to the sti1e in the ordinary, well known manner.

The stile and the door are provided on their fases with braokets 3. These brackets are substantially the same in eonstruction and therefore a detailed deseription of the one shown in Fig. 2 Wi11 suifiee to impart a definite understanding of both. Said bracket is formed of a single piece of sheet meta1 and comprises spaced p1ates 4= having registered apertures 5 at intervals of their length, a bight 6 connecting the inner portions of said plates, and apertured ars 7 reaohing at right angles to the inner ends of the p1ates and adapted to be opposed to" and oonnected with the sti1e 1 er door 2. By virtue of the plura1ity of apertures 5 in the plates 4, the 1evers hereinafter descrbed aan he readily adjusted to regulate the ten- 3. This arm 16, at an intermediate point of its length, is pivotally connected by a pintle 10 Withthe free end portion of the arm 10, and to the free end of said arm 16 is connected, preferably in a detaehable marmer, one end of a retraetile spring 22.

The ether end of said spring is connected With the stile 1, the eonnection being preferably a tension-regulating eonneetion effeeted through the sti1e braeket 3, a 100pshaped arm 42 pivotally connected to said bracket, a bolt 26 extending through an aperture in the bight of the arm 42, and a nut 28 mounted on the bolt and arranged in front of one or more c0i1s of the spring 22.

In operation, opening of the door will be attended by outward swinging of the outer ends of both arms and the expansion of the spring, and consequently when the door is released the contraction of the spring Wil1 operate in a powerful manner to close the door and yieldingiy retain the same in its closed position.

The modification of Fig. 3 includes brackets 3 similar to those of Fig. 1, and in addition a long horizontally-swinging arm 16" pivoted to the sti1e bracket, a short arm 10" pivoted to the door bracket and to the arm 16" at an intermediate point in the length of the lat ter, and a retraotile spring 22" connected at one end to the door bracket, preferably in a detachable marmer and having one or more eoils at its opposite end arranged back of a nut 28" mounted on a bolt 26" whieh in turn, extends through an aperture, in the extended portion of the arm 16" and has a kerfed head back of said arm in order that the bolt can be eonveniently turned to regulate the tension of the spring.

In the operation of the embodiment shown in Fig. 3 the arms 10" and 16 are swung out wardly and the spring 22 is stretched incidental t0 opening of the door, and therefore the spring operates wheri the door is released t0 strongly and quickly return the door te its closed position.

By reference t0 Fig. 1, it Wll be noted that-the bracket 3 is preferably proVded With a laterally extending inner portion 4. The connection between the spring 22 and the said portion 4 is by preference a tensionregulating connecton efected through a loop-shaped arm 42, preferably connected t0 said portion 4:, thebolt 26 extending through an aperture in the bight of the arm 42 and the nut 28 mounted en the bolt and arranged in front of one or more c0ils of the spring 22 as before described. It will be manifest from the foregoing that in each embodiment 0 my invention the brackets are conveniently applied to the enter sides of the stile and door; a1s0, that the horizontally swinging arms and the re tractile Spring in each embodiment are arranged entirely in front of the stile and door; with the result that access may be readi1y gained to all of the parts or repair 0r adjustment purposes.

IIa"ing described my invention, what I claim and desire t0 secure by Letters Patent, is:

1. In a door closing device, the combination of a door frame, a door hinged thereto, a bracket on the outer side of the frame and extending laterally therefrom, a bracket on the outer side Of the door and extendinglaterally therefrom, a horizontally-swinging arm pimted to the door bracket, a horizontaily-swinging arm pivoted to t1 1e frame bracket and pivoted at an intermed1ate point of its length to the first-named arm and having a portion extending beyond the latter, and a retractile spring connected With and extending het-ween the extended portion of the secnd-named arm and one of the brack ets; the said arms and the spring being arranged entirely in front of the frame and the do0r.

2. In a door c1osing device, the combina tion of a door frame, a door hinged thereto, a bracket on the outer side of the frame and extending laterally therefrom, a brackct on the outer side of the door and extending latera1ly thercfrom, a hoiizontally swinging arm pivoted to the door bracket, a horizontallyswinging curvilinear arm pivoted to the frame bracket and pi voted at an intermediate point of its length to the firstnamed arm and having a portion extending bcyond the latter point of connection and toward the outer side of the door, and a retractile spring arranged in substantial[par a11e1 relation to the door and connected with and extending between the extended portion 0f the secondnamed arm and the frame bracket; the said arms and the spring being arranged entirely in front of the frame and the door.

. In testimony whereof. I aifix my signature in presence of two witnesses.
